Thanks everyone for the feedback. I added rooms (now two of them are filled with crystals) in the game and have slightly improved player controls.

The controls need some work, maybe allow moving diagonally?

But nonetheless, nice job submitting! :)

I love the hazard idea, you kind of needed to re-calibrate on the fly. Controls were a bit wonky but other than that I liked it!

I wish there more level. Also the controls are a bit off. Overall pretty fun game.

I enjoyed the combination of graphics and music. The animations were fine.

At first I thought the red crystals were bad and the green ones good ^^ Maybe make all green or give more colors so the player does not associate color with anything.

Fun little game otherwise! More levels please :)

The game was a nice short little puzzle. I wanted there to be more of it, which is always a good thing for a demo.

Good game, didn't go with the theme, nothing happened when you won. I liked the traps mechanic and the visuals and audio were both good.

Nice idea. Topdown look adds to tension when finding out the hidden hazards. Couldn't figure out "space" for a while (:

I liked it, the input felt a little slow and my dumbself didn't know how to get 3 of the gems, but besides that, pretty solid for the timespan.
